Hay pellets for burning. They burn just as well as wood pellets, but hay pellets are cheaper.

Description

Hay pellets are a relatively new idea in heating and are becoming increasingly popular. Reasons to this vary - increasing energy consumption, rising prices of traditional energy resources, lack of raw material for production of woodchip pellets, development of heating technologies.
Hay pellets burn just as well as wood pellets. The efficiency is calculated by the amount burned minus the ash content. So grass based pellets usually have a 1%*2% higher ash content, but after burning the ash can be used as ecological fertilizer in the farming. Not only are the Hay pellets environmentally friendly they’re wallet friendly too!
